My favorite load for 65 CM is the 120 gr. Ballistic Tip over 39.5 gr. of Varget, F210M primer all in Hornady brass. I get a tad over 2900 fps and great accuracy. As always, work up to that load. It’s fine in my Fieldcraft.
I know I’m not taking advantage of the heavy bullet/long range capabilities of the cartridge, but it works great for my needs.
